      could you please explain how to take symmetry boundary condition


       


      The fluid flow and heat transfer simulations have been carried


      out using commercial CFD tool, ANSYS CFX 14.5. The


      coolant used in the experiments is water and the same is used


      in CFD studies for validation and parametric studies. A single


      phase laminar fluid flow and heat transfer analysis is carried


      out. Continuum flow is assumed inside the micro heat exchanger.


      The flow field and heat transfer characteristics through the


      micro channel heat sink are obtained by solving the threedimensional


      governing equations namely the following: continuity


      for conservation of mass, Navier-Stokes equation for


      conservation of momentum and energy equation. Fluid


      domain of water and solid domain of micro-channel heat sink


      are meshed separately and proper interface is defined in


      ANSYS CFX Pre for capturing the flow physics. The meshing


      of fluid and solid domains is carried out in ICEMCFD tool


      using blocking methodology. Only one fluid channel and two


      solid domains, each half on either side of the fluid domain,


      are considered in the analysis and the entire model with 122


      channels is not simulated. Symmetry boundary condition is


      applied on either side of the solid domains of the MCHS


      assembly.

      Hello Mahesh,

      You can search in Youtube" on simulation of heat transfer and fluid flow in heat sink using ANSYS FLUENT". You will get the right tutorial which explains step by step procedure from geometry to post processing.
      Please note that the tutorial is not prepared by ANSYS.

      Hope you get the right tutorial and helpful to you.
